In reply to exiled_northerner:
I've the MyTiMug (or however the capitalisation goes) 650 and use it with a Vango micro stove - basically an equivalent to the Alpkit Kraku, pocket rocket and similar stoves.
General mode of operation is just to boil water in it rather than try and make anything fancy. Anything needing "cooking" are essentially boil in the bag type foods. Saves on washing up and in deciding whether to have a brew or cook food first. You can use either commercial freeze dried meals or make your own, plenty of books/websites for the latter.
A Coleman 100g gas cylinder will go inside the mug plus you can fit the stove, lighter and quite a bit more in as well (worth having something soft like tea bags you can stuff in to stop the rattling).
I've found that you do need something to hold the handles when removing from the stove, a buff or similar will do. Usually the mug itself is cool enough to drink from within a minute or two of removing it from the stove. Could be worth making a little insulated jacket for it so that it doesn't cool down too much.
I've made one of those meths burners from a beer can but not used it in anger so can't comment on how efficient or otherwise it is. Since that was my first effort at making one, it might not be quite right!
Worth having a go at making one yourself.
